It was intended that, for principal services, 12-car formations would operate with a 4-RES unit (providing the kitchen and dining facilities for the train) sandwiched by two 4-COR units
For services from London Victoria to Portsmouth via Dorking, another 26 4-COR units (numbered 3130–3155) were built. These also ran as 12 car units, but with a 4-BUF in place of the 4-RES.
The last scheduled passenger service was on the 31st July 1971, although officially they were withdrawn in 1972.
